Abstract
An oscillating structure with piezoelectric actuation includes first and second torsional elastic elements constrained to respective portions of a fixed supporting body and defining an axis of rotation. A mobile element is positioned between, and connected to, the first and second torsional elastic elements by first and second rigid regions. A first control region is coupled to the first rigid region and includes a first piezoelectric actuator. A second control region is coupled to the second rigid region and includes a second piezoelectric actuator. The first and second piezoelectric actuators are configured to cause local deformation of the first and second control regions to induce a torsion of the first and second torsional elastic elements.
